## Description

products within the Advanced Technologies Business Unit. This role will support a variety of programs that are defining, creating, and fielding the next-generation RF technologies and capabilities that are needed by our national defense force to meet and surpass the threats of today and beyond. This position is an onsite role in El Segundo, CA. What You Will Do: * Design, implement, and validate algorithms for RF digital signal processing, data fusion, target tracking, and/or automated resource management, using both simulated and real-time demonstration data

 * Model and simulate of sensor phenomenology, both for RF sensors (e.g. radar, Air-to-Air capabilities, Air-to-Ground capabilities, Electronic Support Measures) and sensors outside the RF spectrum (e.g., EO/IR)
 * Collaborate in a cross-functional team of systems, software, and hardware engineers in efforts including development and/or integration of real-time software,
 * Support modeling and simulation, field demonstrations, processing real-world data, trade studies in system and algorithm design, and requirements allocation and verification
 * Develop and extend automated analysis tools for reducing large data sets and producing analysis outputs, e.g., RF sensor I/Q data, sensor measurement data, tracker measurement data
 * Interface with technical and program team leads on a regular basis in a fast-paced environment
 * Experience with communicating between program stakeholders
